For me the best thing about the T2 is the ability to load in your own WAV files.
If you all think the sweet, mega and SA sounds are good, try creating your own samples. They don't even have to be huge amounts of megabytes. I've got a 5mb alto sax and I think it's even more realistic than the SA sax, it's got more warmth to it.
Because these samples are stored as TVN files you can also give the styles parts access to these sounds. Swapping the guitars, sax, piano etc from the styles to your own sampled sounds brings a whole new life to the styles, not that they were ever bad to start off with, but once you try it there's no going back.
